TECHNICAL FIELD

The present disclosure relates to the field of information processingtechnology, and more particularly, to a method for indicating a positionof a synchronous signal block, a network apparatus, a terminalapparatus, and a computer storage medium.

BACKGROUND

The synchronous channels in the LTE system are PSS and SSS signals, andthe reference signal for a terminal to measure RRM is a CRS or CSI-RSsignal. In a 5G NR system design, 3GPP has reached a conclusion that anetwork apparatus sends an SS burst set containing a plurality of SSblocks to the terminal, and each SS block includes PSS, SSS, and PBCH.Based on the implementation of the base station, each SS block maycorrespond to one downlink beam. The terminal searches for the SS blockin the system bandwidth to acquire time-frequency synchronization andPBCH information, and performs RRM measurement based on the SSS and theDMRS of the PBCH.

At present, 3GPP has also reached a conclusion that a SS block positionfor actual transmission in one SS burst set may be notified to theterminal via a broadcast signaling RMSI by a serving cell of theterminal in a manner of bitmap.

However, the processing method of the existing technology mentionedabove is only for the current cell to obtain the synchronous signal, andit cannot further guarantee to reduce the terminal measurement time andpower consumption of the terminal apparatus.

DETAILED DESCRIPTION

In order to have a more detailed understanding of the characteristic andtechnical contents of the embodiments of the present disclosure, theimplementation of the embodiments of the present disclosure will bedescribed below with reference to the drawings. The accompanyingdrawings are for reference only, rather than limiting the embodiments ofthe present disclosure.

First Embodiment

This embodiment provides a method for indicating a position of asynchronous signal block. As shown in FIG. 1, the method includes thefollowing steps.

In step 101, a transmission position of a synchronous signal block of atleast one first type of cell is determined.

In step 102, the transmission position of the synchronous signal blockof the at least one first type of cell is sent to a terminal apparatusby a signaling, the terminal apparatus being located within a range of asecond type of cell managed by the network apparatus.

Here, the network apparatus may be a base station, for example, may bean eNB, a gNB, or other apparatus. Alternatively, the network apparatusmay be other network apparatus, as long as the apparatus can provide afunction of accessing the mobile communication network for the terminalapparatus.

It should be further noted that the first type of cell refers to a celladjacent to the cell where the terminal apparatus is located, which maybe a neighboring cell.

In addition, it should be understood that, the terminal apparatus beingwithin the cell managed by the network apparatus may be that theterminal apparatus is located in one of a plurality of cells managed bythe network apparatus.

For a non-carrier aggregation (CA) scenario, the cell in which theterminal apparatus is located may be referred to as a second type ofcell, and the second type of cell may also be referred to as a servingcell of the terminal apparatus. In this embodiment, the second type ofcell in which the terminal is located and the first type of cell (thatis, the neighboring cell) may be cells managed by the same networkapparatus, and may also be cells managed by different networkapparatuses.

For a CA scenario, a Primary cell (i.e., P cell) in the cell in whichthe terminal apparatus is located may be referred to as a second type ofcell; other cells except the P cell (including an S cell having theterminal apparatus, that is, the secondary cell) are all classified intothe first type of cell. In the scenario, the second type of cell inwhich the terminal is located and the first type of cell (that is, theneighboring cell) may be cells managed by the same network apparatus,and may also be cells managed by different network apparatuses.

In the above step 101, the manners for the network apparatus todetermine the transmission position of the actual synchronous signalblock (SS block) of other cells adjacent to the network apparatus mayinclude the followings.

In a first manner, the transmission position of the synchronous signalblock of at least one first type of cell is acquired by an X2 interfaceor an S1 interface. (In the present embodiment, the first type of cellbeing a neighboring cell is taken as an example for subsequentdescription)

Specifically, the network apparatus may query the base station apparatusof other cells adjacent to itself by the S1 interface and the X2interface, and the base station apparatus of other cells notifies theactual transmission position of the SS block of other cells to thenetwork apparatus by the X2 interface and the S1 interface.

The querying and notifying process may be performed periodically. Theperiod needs to be smaller than a period in which the base stationapparatus updates the actual transmission position of the SS block.

It should be noted that, this manner is more suitable for the scenariowhere the first type of cell and the cell in which the terminalapparatus is located are managed by different network apparatuses.

In a second manner, a broadcast message sent by a network apparatuscorresponding to at least one first type of cell is acquired; and

a transmission position of a synchronous signal block of at least onefirst type of cell is acquired from the broadcast message.

The network apparatus acquires the transmission position of an actual SSblock of other cells adjacent to the network apparatus by receiving andreading the broadcast message of other cells adjacent to the networkapparatus.

Specifically, since the network apparatus may notify the actual SS blocktransmission position of the local cell by the broadcast message RMSI,the network apparatus may periodically read the broadcast message ofother cells adjacent to the network apparatus and obtain the actualtransmission position of the SS block of the neighboring cell.

It should be noted that, this manner is more suitable for the scenariowhere the first type of cell and the cell where the terminal apparatusis located are managed by different network apparatuses.

In addition to the above two manners, for the scenario in which the cellin which the terminal device is located and the first type of cell (thatis, the neighboring cell) are both managed by the same networkapparatus, the method for acquiring the transmission position of thesynchronous signal block of the neighboring cell may be directlyacquired from the cell management information of the network apparatus,which will not elaborated here.

In step 102, the transmitting, by the signaling, the transmissionposition of the synchronous signal block of the at least one first typeof cell to the terminal apparatus, includes:

generating a bitmap based on the transmission position of thesynchronous signal block of the at least one first type of cell, andtransmitting the bitmap to the terminal apparatus by the signaling.

The method for sending the bitmap to the terminal apparatus may be: thenetwork apparatus notifies the terminal, by a broadcast signaling, theactual transmission position of the SS block of other cells;

or, the network apparatus notifies the terminal, by a RRC dedicatedsignaling, the actual transmission position of the SS block of othercells.

The generating the bitmap based on the transmission position of thesynchronous signal block of the at least one first type of cell, andtransmitting the bitmap to the terminal apparatus by signaling,includes:

when the first type of cell is in a synchronous state with the cellmanaged by the network apparatus, generating the bitmap of thetransmission position(s) of the synchronous signal block(s) includingall the first type of cell(s) based on transmission position(s) of thesynchronous signal block(s) of all the first type of cell(s); and

transmitting, by the signaling, the bitmap including the transmissionposition(s) of the synchronous signal block(s) of all the first type ofcell(s) to the terminal apparatus.

That is, the network apparatus aggregates the transmission positions ofthe synchronous signal blocks of all neighboring cells into one bitmap,and notifies the actual transmission position of the SS block of othercells in the form of a bitmap. That is, the bitmap contains the completeset of actual SS block positions of all other cells needing to notify.

For example, referring to FIG. 2, a network apparatus and a terminaloperate in a frequency band of 3-6 GHz, and one SS burst set maytransmit up to eight SS blocks. Based on the actual deploymentrequirement and specific implementation of the network, the numbers ofthe SS blocks transmitted by different base station apparatuses areshown in FIG. 2.

For example, cell 1, cell 2, cell 3, and 4 are mutually neighboringcells, the SS block position actually transmitted by cell 1 is the firstposition of 8 candidate SS block positions, and cell 2 corresponds tothe first and second positions; cell 3 corresponds to the second andfour positions; and cell 4 corresponds to the first and third positions.

For cell 1, cell 2, cell 3 and cell 4 are neighboring cells, and cell 2,cell 3 and cell 4 use the first, second, third, and fourth SS blockpositions, when cell 1 uses a bitmap to notify the actual transmissionposition of the SS block of the neighboring cell of cell 1 to the UEserved by cell 1, the bitmap is: “11110000”, where “1” indicates thatthe SS block is transmitted at this candidate position, and “0”indicates that the SS block is not transmitted at this candidateposition.

For cell 3, cell 1, cell 2 and cell 4 are neighboring cells, and cells1, 2 and 4 use the first, second, and third SS block positions, whencell 3 uses a bitmap to notify the actual transmission position of theSS block of the neighboring cell of cell 3 to the UE served by cell 3,the bitmap is: “11100000”, where “1” indicates that the SS block istransmitted at this candidate position, and “0” indicates that the SSblock is not transmitted at this candidate position.

For cell 4, cell 1, cell 2 and cell 3 are neighboring cells, and cell 1,cell 2 and cell 3 use the first, second, and fourth SS block positions,when cell 4 uses a bitmap to notify the actual transmission position ofthe SS block of the neighboring cell of cell 4 to the UE served by cell4, the bitmap is: “11010000”, where “1” indicates that the SS block istransmitted at this candidate position, and “0” indicates that the SSblock is not transmitted at this candidate position.

The network apparatus notifies the actual transmission position of theSS block of each of other cells to be measured in the form of onebitmap.

Based on the foregoing scheme, the method may further include:transmitting, to the terminal apparatus, a synchronous relationshipbetween the at least one first type of cell and the cell managed by thenetwork apparatus;

wherein, the synchronous relationship includes: the first type of cellis in a synchronous state with the cell managed by the networkapparatus; or, there is a synchronous deviation between the first typeof cell and the cell managed by the network apparatus.

That is, while the network apparatus notifies the terminal of the actualtransmission position of the SS block of other cells by a signaling, thenetwork apparatus notifies the terminal of the synchronous relationshipbetween other cells and the local cell corresponding to the networkapparatus, that is, the synchronous state or the synchronous deviation.

The synchronous state includes: notifying, by the network apparatus,that the local cell corresponding to the network apparatus is in asynchronous state with other neighboring cells, to the terminal.

Correspondingly, when the terminal performs measurement, if the localcell and the neighboring cell are synchronous, the terminal maydetermine the actual position of the SS block transmitted by theneighboring cell. The terminal directly acquires the actual position ofthe SS block of the neighboring cell based on the timing of the localcell.

Different from the foregoing synchronous situation, when there is asynchronous deviation between the local cell and the neighboring cell,the following manner may be adopted:

when there is a synchronous deviation between the at least one firsttype of cell and the cell managed by the network apparatus, sending, tothe terminal apparatus, the synchronous deviation between at least onefirst type of cell and the cell managed by the network apparatus;

generating a bitmap corresponding to each of the neighboring cell(s)based on the transmission position of the synchronous signal block ofthe at least one first type of cell; and

transmitting, by the signaling, the bitmap corresponding to each of thefirst type of cell to the terminal apparatus.

The network apparatus notifies the terminal of the synchronous deviationbetween other cells and the local cell corresponding to the networkapparatus. Correspondingly, when the terminal performs measurement, ifthe local cell and the neighboring cell are not synchronous, theterminal may determine the actual position of the SS block transmittedby the neighboring cell based on the notification information and thedeviation of the timings between the cells. The terminal directlyacquires the actual position of the SS block of the neighboring cell tobe measured based on the timing of the local cell and the timingdeviation of the neighboring cell to be measured.

For example, as shown in FIG. 3, cell 1 and cell 3 are synchronous, cell2 is 0.5 ms backward offset from cell 1 and cell 3, then the firstcandidate SS block position of cell 2 corresponds to the secondcandidate SS block position of cell 2; and cell 4 is 1 ms backwardoffset from cell 1 and cell 3, then the first candidate SS blockposition of cell 4 corresponds to the third candidate SS block positionof cell 1.

For example, cell 1 notifies the terminal of the time deviations betweencell 2, cell 3, cell 4 and cell 1 respectively, and the terminalcombines the actual SS block transmission position of each of the cell2, cell 3 and cell 4, and then may determine the reception time ofactual transmission SS block of each cell.

In addition, the present embodiment may also provide a processing mannerfor a scenario in which a part of the neighboring cells is synchronouswith the local cell and the other part of the neighboring cells is notsynchronous with the local cell:

if there is a synchronous deviation between a first part of the firsttype of cell in the at least one first type of cell and the cell managedby the network apparatus, and a second part of the first type of cell inthe first type of cell is in the synchronous state with the cell managedby the network apparatus; wherein, the first part of the first type ofcell is different from the second part of the first type of cell, andthe first part of the first type of cell and the second part of thefirst type of cell form all the neighboring cells;

then transmitting, to the terminal apparatus, the synchronous deviationbetween the first part of the first type of cell and the cell managed bythe network apparatus; generating a bitmap corresponding to each of thefirst type of cell in the first part of first type of cell based on thetransmission position of the synchronous signal block of the first partof the first type of cell; transmitting, by the signaling, the bitmapcorresponding to each of the first type of cell in the first type ofcell to the terminal apparatus;

and, generating, the bitmap including the transmission position of thesynchronous signal block of the second part of the first type of cellaccording to the transmission position of the synchronous signal blockof the second part of the first type of cell; and transmitting, to theterminal apparatus, the bitmap including the transmission position ofthe synchronous signal block of the second part of the first type ofcell.

For example, in four neighboring cells, the synchronous relationshipbetween the neighboring cells 1, 2 and the local cell is synchronous,and there is a deviation between the neighboring cells 3, 4 and thelocal cell; then, the transmission positions of the synchronous signalblocks of the neighboring cells 1 and 2 are all set in the bitmap andtransmitted to the terminal apparatus; and the synchronous deviation ofthe neighboring cells 3 and 4, the bitmap of the transmission positionof the synchronous signal block of the neighboring cell 3, and thebitmap of the transmission position of the synchronous signal block ofthe neighboring cell 4 are all transmitted to the terminal apparatus.

There is also a processing manner in this embodiment, that is, no matterwhether there is a synchronous deviation between the neighboring celland the local cell, the synchronous deviation of the neighboring celland the bitmap of the transmission position of the synchronous signalblock of the neighboring cell are transmitted to the terminal apparatus.

That is, the synchronous deviation between each of the at least onefirst type of cell and the cell managed by the network apparatus istransmitted to the terminal apparatus;

a bitmap corresponding to each of the first type of cell is generatedbased on the transmission position of the synchronous signal block ofthe at least one first type of cell; and

the bitmap corresponding to each of the first type of cell istransmitted to the terminal apparatus by the signaling.

In this scenario, the synchronous deviation of the neighboring cellsynchronized with the local cell is equal to 0.

Finally, it should be noted that, in this embodiment, the synchronousdeviation of a certain neighboring cell and the bitmap corresponding toa certain neighboring cell may be sent simultaneously or sequentially,which is not limited herein.

It can be seen that by adopting the above scheme, the transmissionposition of the synchronous signal block of the neighboring cell can betransmitted to the terminal apparatus, thereby ensuring that theterminal apparatus can directly measure the neighboring cell at a momentcorresponding to the notified transmission position of the synchronoussignal block of the first type of cell, without performing measurementat other positions, thereby saving terminal measurement time and powerconsumption.

Second Embodiment

This embodiment provides a method for indicating a position of asynchronous signal block, applied to a terminal apparatus. As shown inFIG. 4, the method includes the following steps.

In step 401, a transmission position of a synchronous signal block of atleast one first type of cell sent by a network apparatus via a signalingis received.

In step 402, the synchronous signal block of the at least one first typeof cell is measured based on the transmission position of thesynchronous signal block of the at least one first type of cell.

Here, the network apparatus may be a base station, for example, may bean eNB, a gNB, or other apparatus. Alternatively, the network apparatusmay be other network apparatus, as long as the apparatus can provide afunction of accessing the mobile communication network for the terminalapparatus.

For a non-carrier aggregation (CA) scenario, the cell in which theterminal apparatus is located may be referred to as a second type ofcell, and the second type of cell may also be referred to as a servingcell of the terminal apparatus. In this embodiment, the second type ofcell in which the terminal is located and the first type of cell (thatis, the neighboring cell) may be cells managed by the same networkapparatus, and may also be cells managed by different networkapparatuses.

For a CA scenario, a Primary cell (i.e., P cell) in the cell in whichthe terminal apparatus is located may be referred to as a second type ofcell; other cells except the P cell (including an S cell having theterminal apparatus, that is, the secondary cell) are all classified intothe first type of cell. In the scenario, the second type of cell inwhich the terminal is located and the first type of cell (that is, theneighboring cell) may be cells managed by the same network apparatus,and may also be cells managed by different network apparatuses.

The receiving the transmission position of the synchronous signal blockof the at least one first type of cell sent by the network apparatus viathe signaling, includes:

receiving the signaling from the network apparatus; and

acquiring a bitmap from the signaling, and acquiring, by the bitmap, thetransmission position of the synchronous signal block of at least onefirst type of cell.

The method for transmitting the bitmap to the terminal apparatus may be:the network apparatus notifies the terminal, by a broadcast signaling,the actual transmission position of the SS block of other cells;

or, the network apparatus notifies the terminal, by a RRC dedicatedsignaling, the actual transmission position of the SS block of othercells.

The method further includes:

receiving a synchronous relationship between the at least one first typeof cell sent by the network apparatus and the cell managed by thenetwork apparatus;

wherein, the synchronous relationship includes: the first type of cellis in a synchronous state with the cell managed by the networkapparatus; or, there is a synchronous deviation between the first typeof cell and the cell managed by the network apparatus.

The acquiring the bitmap from the signaling, and acquiring, by thebitmap, the transmission position of the synchronous signal block of theat least one first type of cell, includes:

when there is a synchronous deviation between the first type of cell andthe cell managed by the network apparatus, acquiring, from the bitmap,the transmission position(s) of the synchronous signal block(s) of allthe first type of cell(s).

That is, the network apparatus aggregates the transmission position(s)of the synchronous signal block(s) of all neighboring cell(s) into onebitmap, and notifies the actual transmission position(s) of the SSblock(s) of other cell(s) in the form of one bitmap. That is, the bitmapcontains the complete set of actual SS block positions of all othercells that need to notify.

For example, referring to FIG. 2, a network apparatus and a terminaloperate in a frequency band of 3-6 GHz, and one SS burst set maytransmit up to eight SS blocks. Based on the actual deploymentrequirement and specific implementation of the network, the numbers ofSS blocks transmitted by different base station apparatuses are shown inFIG. 2.

For example, cell 1, cell 2, cell 3, and cell 4 are mutually neighboringcells, the SS block position actually transmitted by cell 1 is the firstposition of 8 candidate SS block positions, and cell 2 corresponds tothe first and second positions; cell 3 corresponds to the second andfourth positions; and cell 4 corresponds to the first and thirdpositions.

For cell 1, cell 2, cell 3 and cell 4 are neighboring cells, and cell 2,cell 3 and cell 4 use the first, second, third, and fourth SS blockpositions, when cell 1 uses a bitmap to notify the actual transmissionposition of the SS block of the neighboring cell of cell 1 to the UEserved by cell 1, the bitmap is: “11110000”, where “1” indicates thatthe SS block is transmitted at this candidate position, and “0”indicates that the SS block is not transmitted at this candidateposition.

For cell 3, cell 1, cell 2 and cell 4 are neighboring cells, and cells1, 2 and 4 use the first, second, and third SS block positions, whencell 3 uses a bitmap to notify the actual transmission position of theSS block of the neighboring cell of cell 3 to the UE served by cell 3,the bitmap is: “11100000”, where “1” indicates that the SS block istransmitted at this candidate position, and “0” indicates that the SSblock is not transmitted at this candidate position.

For cell 4, cell 1, cell 2 and cell 3 are neighboring cells, and cell 1,cell 2 and cell 3 use the first, second, and fourth SS block positions,when cell 4 uses a bitmap to notify the actual transmission position ofthe SS block of the neighboring cell of cell 4 to the UE served by cell4, the bitmap is: “11010000”, where “1” indicates that the SS block istransmitted at this candidate position, and “0” indicates that the SSblock is not transmitted at this candidate position.

The network apparatus notifies the actual transmission position of theSS block of each of other cells to be measured in the form of onebitmap.

When the terminal performs measurement, if the local cell and theneighboring cell are synchronous, the terminal may determine the actualposition of the SS block transmitted by the neighboring cell. Theterminal directly acquires the actual position of the SS block of theneighboring cell based on the timing of the local cell.

Different from the foregoing synchronous situation, when there is asynchronous deviation between the local cell and the neighboring cell,the following manner may be adopted:

when there is a synchronous deviation between the at least one firsttype of cell and the cell managed by the network apparatus,

acquiring, the synchronous deviation between the at least one first typeof cell and the cell managed by the network apparatus; and

acquiring, a bitmap corresponding to each of the first type of cell, andacquiring the transmission position of the synchronous signal block ofeach of the first type of cell based on the bitmap.

First of all, the network apparatus notifies the terminal of thesynchronous deviation between other cell(s) and the local cellcorresponding to the network apparatus. Correspondingly, when theterminal performs measurement, if the local cell and the neighboringcell are not synchronous, the terminal may determine the actual positionof the SS block transmitted by the neighboring cell based on thenotification information and the deviation of the timings between thecells. The terminal directly acquires the actual position of the SSblock of the neighboring cell to be measured based on the timing of thelocal cell and the timing deviation of the neighboring cell to bemeasured.

For example, as shown in FIG. 3, cell 1 and cell 3 are synchronous, cell2 is 0.5 ms backward offset from cell 1 and cell 3, then the firstcandidate SS block position of cell 2 corresponds to the secondcandidate SS block position of cell 2; and cell 4 is 1 ms backwardoffset from cell 1 and cell 3, then the first candidate SS blockposition of cell 4 corresponds to the third candidate SS block positionof cell 1.

For example, cell 1 notifies the terminal of the time deviation of cell2, cell 3, cell 4 and cell 1 respectively, the terminal combines theactual SS block transmission position of each of the cell 2, 3 and 4,and then the terminal may determine the reception time of actualtransmission SS block of each cell.

In addition, the present embodiment may also provide a processing mannerfor a scenario in which a part of the neighboring cells is synchronouswith the local cell and the other part of the neighboring cells is notsynchronous with the local cell:

if there is a synchronous deviation between a first part of the firsttype of cell in at least one first type of cell and the cell managed bythe network apparatus, and a second part of the first type of cell inthe first type of cell is in the synchronous state with the cell managedby the network apparatus; wherein, the first part of the first type ofcell is different from the second part of the first type of cell, andthe first part of the first type of cell and the second part of thefirst type of cell form all the first type of cell;

then acquiring the transmission position of the synchronous signal blockof the first part of the first type of cell based on the bitmap of eachfirst type of cell in the first part of the first type of cell;

and, acquiring, according to the bitmap of the second part of the firsttype of cell, the transmission position of the synchronous signal blockof the second part of the first type of cell.

For example, in four neighboring cells, the synchronous relationshipbetween the neighboring cells 1, 2 and the local cell is synchronous,and the neighboring cells 3 and 4 have a deviation; then, thetransmission positions of the synchronous signal blocks of theneighboring cells 1 and 2 are all set in the bitmap and transmitted tothe terminal apparatus; the synchronous deviation of the neighboringcells 3 and 4, and the bitmap of the transmission position of thesynchronous signal block of the neighboring cell 3, and the bitmap ofthe transmission position of the synchronous signal block of theneighboring cell 4 are all transmitted to the terminal apparatus.Correspondingly, the terminal apparatus performs measurement on theneighboring cells 1 and 2 based on the bitmap of the transmissionposition of the synchronous signal block including the neighboring cells1 and 2; and then, based on the synchronous deviation of the neighboringcells 3 and 4 and the respective bitmaps, perform the measurement at thetransmission positions of the synchronous signal blocks of theneighboring cells 3 and 4 respectively.

There is also a processing manner in the present embodiment, that is, nomatter whether there is a synchronous deviation between the neighboringcell and the local cell, the synchronous deviation of the neighboringcell and the bitmap of the transmission position of the synchronoussignal block of the neighboring cell are transmitted to the terminalapparatus.

That is, the synchronous deviation between each of the at least onefirst type of cell and the cell managed by the network apparatus istransmitted to the terminal apparatus;

the bitmap corresponding to each of the first type of cell is acquired,and the transmission position of the synchronous signal block of each ofthe first type of cell is acquired from the bitmap.

In this scenario, the synchronous deviation of the neighboring cellsynchronized with the local cell is equal to 0.

Finally, it should be noted that, in this embodiment, the synchronousdeviation of a certain neighboring cell and the bitmap corresponding toa certain neighboring cell may be sent simultaneously or sequentially,which is not limited herein.

It can be seen that by adopting the above scheme, the transmissionposition of the synchronous signal block of the neighboring cell can betransmitted to the terminal apparatus, thereby ensuring that theterminal apparatus can directly measure the neighboring cell at a momentcorresponding to the notified transmission position of the synchronoussignal block of the first type of cell, without performing measurementat other positions, thereby saving terminal measurement time and powerconsumption.

The communication unit 52 is configured to send the signaling to theterminal apparatus.

Here, the network apparatus may be a base station, for example, may bean eNB, a gNB, or other apparatus. Alternatively, the network apparatusmay be other network apparatus, as long as the apparatus can provide afunction of accessing the mobile communication network for the terminalapparatus.

It should be further noted that the first type of cell refers to a celladjacent to the cell where the terminal apparatus is located, which maybe a neighboring cell.

In addition, it should be understood that, the terminal apparatus beingwithin the cell managed by the network apparatus, may be that theterminal apparatus is located in one of a plurality of cells managed bythe network apparatus.

For a non-carrier aggregation (CA) scenario, the cell in which theterminal apparatus is located may be referred to as a second type ofcell, and the second type of cell may also be referred to as a servingcell of the terminal apparatus. In the embodiment, the second type ofcell in which the terminal is located and the first type of cell (thatis, the neighboring cell) may be cells managed by the same networkapparatus, and may also be cells managed by different networkapparatuses.

For a CA scenario, a Primary Cell (i.e., P cell) in the cell in whichthe terminal apparatus is located may be referred to as a second type ofcell; and other cells except the P cell (including an S cell having theterminal apparatus, that is, the secondary cell) are all classified intothe first type of cell. In the scenario, the second type of cell inwhich the terminal is located and the first type of cell (that is, theneighboring cell) may be cells managed by the same network apparatus,and may also be cells managed by different network apparatuses.

In a first manner, the processing unit 51 is configured to acquire thetransmission position of the synchronous signal block of at least onefirst type of cell by an X2 interface or an S1 interface. (In thepresent embodiment, the first type of cell being a neighboring cell istaken as an example for subsequent description)

Specifically, the network apparatus may query the base station apparatusof other cells adjacent to itself by the S1 interface and the X2interface, and the base station apparatus of other cells notifies theactual transmission position of the SS block of other cells to thenetwork apparatus by the X2 interface and the S1 interface.

The above querying and notifying process may be performed periodically.The period needs to be smaller than a period in which the base stationapparatus updates the actual transmission position of the SS block.

It should be noted that, this manner is more suitable for the scenariowhere the first type of cell and the cell in which the terminalapparatus is located are managed by different network apparatuses.

In a second manner, the processing unit 51 is configured to acquire abroadcast message sent by a network apparatus corresponding to at leastone first type of cell; and

acquire a transmission position of a synchronous signal block of atleast one first type of cell is from the broadcast message.

The network apparatus acquires the actual transmission position of theSS block of other cells adjacent to the network apparatus by receivingand reading the broadcast message of other cells adjacent to the networkapparatus.

Specifically, since the network apparatus may notify the actual SS blocktransmission position of the local cell by the broadcast message RMSI,the network apparatus may periodically read the broadcast message ofother cells adjacent to the network apparatus and obtain the actualtransmission position of the SS block of the neighboring cell.

It should be noted that, this manner is more suitable for the scenariowhere the first type of cell and the cell where the terminal apparatusis located are managed by different network apparatuses.

In addition to the above two manners, for the scenario in which the cellin which the terminal device is located and the first type of cell (thatis, the neighboring cell) are both managed by the same networkapparatus, the method for acquiring the transmission position of thesynchronous signal block of the neighboring cell may be directlyacquired from the cell management information of the network apparatus,which will not be elaborated here.

The processing unit 51 is configured to generate a bitmap based on thetransmission position of the synchronous signal block of the at leastone first type of cell, and transmit the bitmap to the terminalapparatus by the signaling.

The method for sending the bitmap to the terminal apparatus may be: thenetwork apparatus notifies the terminal, by a broadcast signaling, theactual transmission position of the SS block of other cells;

or, the network apparatus notifies the terminal, by a RRC dedicatedsignaling, the actual transmission position of the SS block of othercells.

The processing unit 51 is configured to, when the first type of cell isin a synchronous state with the cell managed by the network apparatus,generate the bitmap of the transmission position(s) of the synchronoussignal block(s) including all the first type of cell(s) based ontransmission position(s) of the synchronous signal block(s) of all thefirst type of cell(s); and

transmit, by the signaling, the bitmap including the transmissionposition(s) of the synchronous signal block(s) of all the first type ofcell(s) to the terminal apparatus.

That is, the network apparatus aggregates the transmission positions ofthe synchronous signal blocks of all neighboring cells into one bitmap,and notifies the actual transmission position of the SS block of othercells in the form of a bitmap. That is, the bitmap contains the completeset of actual SS block positions of all other cells needing to notify.

For example, referring to FIG. 2, a network apparatus and a terminaloperate in a frequency band of 3-6 GHz, and one SS burst set maytransmit up to eight SS blocks. Based on the actual deploymentrequirement and specific implementation of the network, the numbers ofthe SS blocks transmitted by different base station apparatuses areshown in FIG. 2.

For example, cell 1, cell 2, cell 3, and cell 4 are mutually neighboringcells, the SS block position actually transmitted by cell 1 is the firstposition of 8 candidate SS block positions, and cell 2 corresponds tothe first and second positions; cell 3 corresponds to the second andfourth positions; and cell 4 corresponds to the first and thirdpositions.

For cell 1, cell 2, cell 3 and cell 4 are neighboring cells, and cell 2,cell 3 and cell 4 use the first, second, third, and fourth SS blockpositions, when cell 1 uses a bitmap to notify the actual transmissionposition of the SS block of the neighboring cell of cell 1 to the UEserved by cell 1, the bitmap is: “11110000”, where “1” indicates thatthe SS block is transmitted at this candidate position, and “0”indicates that the SS block is not transmitted at this candidateposition.

For cell 3, cell 1, cell 2 and cell 4 are neighboring cells, and cells1, 2 and 4 use the first, second, and third SS block positions, whencell 3 uses a bitmap to notify the actual transmission position of theSS block of the neighboring cell of cell 3 to the UE served by cell 3,the bitmap is: “11100000”, where “1” indicates that the SS block istransmitted at this candidate position, and “0” indicates that the SSblock is not transmitted at this candidate position.

For cell 4, cell 1, cell 2 and cell 3 are neighboring cells, and cells1, 2 and 3 use the first, second, and fourth SS block positions, whencell 4 uses a bitmap to notify the actual transmission position of theSS block of the neighboring cell of cell 4 to UE served by cell 4, thebitmap is: “11010000”, where “1” indicates that the SS block istransmitted at this candidate position, and “0” indicates that the SSblock is not transmitted at this candidate position.

The network apparatus notifies the actual transmission position of theSS block of each of other cells to be measured in the form of onebitmap.

Based on the foregoing scheme, the method may further include:transmitting, to the terminal apparatus, a synchronous relationshipbetween the at least one first type of cell and the cell managed by thenetwork apparatus;

wherein, the synchronous relationship includes: the first type of cellis in a synchronous state with the cell managed by the networkapparatus; or, there is a synchronous deviation between the first typeof cell and the cell managed by the network apparatus.

That is, while the network apparatus notifies the terminal of the actualtransmission position of the SS block of other cells by a signaling, thenetwork apparatus notifies the terminal of the synchronous relationshipbetween other cells and the local cell corresponding to the networkapparatus, that is, the synchronous state or the synchronous deviation.

The synchronous state includes: notifying, by the network apparatus,that the local cell corresponding to the network apparatus is in asynchronous state with other neighboring cell(s), to the terminal.

Correspondingly, when the terminal performs measurement, if the localcell and the neighboring cell are synchronous, the terminal maydetermine the actual position of the SS block transmitted by theneighboring cell. The terminal directly acquires the actual position ofthe SS block of the neighboring cell based on the timing of the localcell.

Different from the foregoing synchronous situation, when there is asynchronous deviation between the local cell and the neighboring cell,the following manner may be adopted.

The processing unit 51 is configured to send, when there is asynchronous deviation between the first type of cell and the cellmanaged by the network apparatus, to the terminal apparatus, thesynchronous deviation between at least one first type of cell and thecell managed by the network apparatus;

generate a bitmap corresponding to each of the neighboring first type ofcell(s) based on the transmission position of the synchronous signalblock of the at least one first type of cell; and

transmit, by the signaling, the bitmap corresponding to each of thefirst type of cell to the terminal apparatus.

First of all, the network apparatus notifies the terminal of thesynchronous deviation between other cells and the local cellcorresponding to the network apparatus. Correspondingly, when theterminal performs measurement, if the local cell and the neighboringcell are not synchronous, the terminal may determine the actual positionof the SS block transmitted by the neighboring cell based on thenotification information and the deviation of the timings between thecells. The terminal directly acquires the actual position of the SSblock of the neighboring cell to be measured based on the timing of thelocal cell and the timing deviation of the neighboring cell to bemeasured.

For example, as shown in FIG. 3, cell 1 and cell 3 are synchronous, cell2 is 0.5 ms backward offset from cell 1 and cell 3, then the firstcandidate SS block position of cell 2 corresponds to the secondcandidate SS block position of cell 1; and cell 4 is 1 ms backwardoffset from cell 1 and cell 3, then the first candidate SS blockposition of cell 4 corresponds to the third candidate SS block positionof cell 1.

For example, cell 1 notifies the terminal of the time deviations betweencell 2, cell 3, cell 4 and cell 1 respectively, and the terminalcombines the actual SS block transmission position of each of the cell2, cell 3 and cell 4, and then may determine the reception time ofactual transmission SS block of each cell.

In addition, the present embodiment may also provide a processing mannerfor a scenario in which part of neighboring cells is synchronous withthe local cell and the other part of the neighboring cells is notsynchronous with the local cell:

if there is a synchronous deviation between a first part of the firsttype of cell in the at least one first type of cell and the cell managedby the network apparatus, and a second part of the first type of cell inthe first type of cell is in the synchronous state with the cell managedby the network apparatus; wherein, the first part of the first type ofcell is different from the second part of the first type of cell, andthe first part of the first type of cell and the second part of thefirst type of cell form all the first type of cells; and

then transmitting, to the terminal apparatus, the synchronous deviationbetween the first part of the first type of cell and the cell managed bythe network apparatus; generating a bitmap corresponding to each of thefirst type of cell in the first part of first type of cell based on thetransmission position of the synchronous signal block of the first partof the first type of cell; transmitting, by the signaling, a bitmapcorresponding to each of the first type of cell in the first type ofcell to the terminal apparatus;

and, generating, the bitmap including the transmission position of thesynchronous signal block of the second part of the first type of cellaccording to the transmission position of the synchronous signal blockof the second part of the first type of cell; and transmitting, to theterminal apparatus, the bitmap including the transmission position ofthe synchronous signal block of the second part of the first type ofcell.

For example, in four neighboring cells, the synchronous relationshipbetween the neighboring cells 1, 2 and the local cell is synchronous,and there is a deviation between the neighboring cells 3, 4 and thelocal cell; then, the transmission positions of the synchronous signalblocks of the neighboring cells 1 and 2 are all set in the bitmap andtransmitted to the terminal apparatus; and the synchronous deviation ofthe neighboring cells 3 and 4, the bitmap of the transmission positionof the synchronous signal block of the neighboring cell 3, and thebitmap of the transmission position of the synchronous signal block ofthe neighboring cell 4 are all transmitted to the terminal apparatus.

There is also a processing manner in the embodiment, that is, no matterwhether there is a synchronous deviation between the neighboring celland the local cell, the synchronous deviation of the neighboring celland the bitmap of the transmission position of the synchronous signalblock of the neighboring cell are transmitted to the terminal apparatus.

That is, the processing unit 51 is configured to transmit thesynchronous deviation between each of the at least one first type ofcell and the cell managed by the network apparatus to the terminalapparatus;

generate a bitmap corresponding to each of the first type of cell basedon the transmission position of the synchronous signal block of the atleast one first type of cell; and

transmit the bitmap corresponding to each of the first type of cell tothe terminal apparatus by the signaling.

In this scenario, the synchronous deviation of the neighboring cellsynchronized with the local cell is equal to 0.

Finally, it should be noted that, in this embodiment, the synchronousdeviation of a certain neighboring cell and the bitmap corresponding toa certain neighboring cell may be transmitted simultaneously orsequentially, which is not limited herein.

It can be seen that by adopting the above scheme, the transmissionposition of the synchronous signal block of the neighboring cell can betransmitted to the terminal apparatus, thereby ensuring that theterminal apparatus can directly measure the neighboring cell at a momentcorresponding to the notified transmission position of the synchronoussignal block of the notified first type of cell, without performingmeasurement at other positions, thereby saving terminal measurement timeand power consumption.

Fourth Embodiment

This embodiment provides a terminal apparatus. As shown in FIG. 6, theapparatus includes: an information receiving unit 61 and a measuringunit 62.

The information receiving unit 61 is configured to receive atransmission position of the synchronous signal block of at least onefirst type of cell sent by a network apparatus via a signaling.

The measuring unit 62 is configured to measure the synchronous signalblock of the at least one first type of cell based on the transmissionposition of the synchronous signal block of the at least one first typeof cell.

Here, the network apparatus may be a base station, for example, may bean eNB, a gNB, or other apparatus. Alternatively, the network apparatusmay be other network apparatus, as long as the apparatus can provide afunction of accessing the mobile communication network for the terminalapparatus.

For a non-carrier aggregation (CA) scenario, the cell in which theterminal apparatus is located may be referred to as a second type ofcell, and the second type of cell may also be referred to as a servingcell of the terminal apparatus. In this embodiment, the second type ofcell in which the terminal is located and the first type of cell (thatis, the neighboring cell) may be cells managed by the same networkapparatus, and may also be cells managed by different networkapparatuses.

For a CA scenario, a Primary cell (i.e., P cell) in the cell in whichthe terminal apparatus is located may be referred to as a second type ofcell; other cells except the P cell (including an S cell having theterminal apparatus, that is, the secondary cell) are all classified intothe first type of cell. In the scenario, the second type of cell inwhich the terminal is located and the first type of cell (that is, theneighboring cell) may be cells managed by the same network apparatus,and may also be cells managed by different network apparatuses.

The information receiving unit is configured to receive the signalingfrom the network apparatus.

Accordingly, the measuring unit is configured to acquire a bitmap fromthe signaling, and acquire, by the bitmap, the transmission position ofthe synchronous signal block of at least one first type of cell.

The method for transmitting the bitmap to the terminal apparatus may be:the network apparatus notifies the terminal, by a broadcast signaling,the actual transmission position of the SS block of other cells;

or, the network apparatus notifies the terminal, by a RRC dedicatedsignaling, the actual transmission position of the SS block of othercells.

The information receiving unit 61 is configured to receive a synchronousrelationship between the at least one first type of cell sent by thenetwork apparatus and the cell managed by the network apparatus;

wherein, the synchronous relationship includes: the first type of cellis in a synchronous state with the cell managed by the networkapparatus; or, there is a synchronous deviation between the first typeof cell and the cell managed by the network apparatus.

The measuring unit 62 is configured to, when there is a synchronousdeviation between the first type of cell and the cell managed by thenetwork apparatus, acquire from the bitmap, the transmission position(s)of the synchronous signal block(s) of all the first type of cell(s).

That is, the network apparatus aggregates the transmission position(s)of the synchronous signal block(s) of all neighboring cell(s) into onebitmap, and notifies the actual transmission position(s) of the SSblock(s) of other cell(s) in the form of one bitmap. That is, the bitmapcontains the complete set of actual SS block positions of all othercells that need to notify.

For example, referring to FIG. 2, a network apparatus and a terminaloperate in a frequency band of 3-6 GHz, and one SS burst set maytransmit up to eight SS blocks. Based on the actual deploymentrequirement and specific implementation of the network, the numbers ofSS blocks transmitted by different base station apparatuses are shown inFIG. 2.

For example, cell 1, cell 2, cell 3, and cell 4 are mutually neighboringcells, the SS block position actually transmitted by cell 1 is the firstposition of 8 candidate SS block positions, and cell 2 corresponds tothe first and second positions; cell 3 corresponds to the second andfourth positions; and cell 4 corresponds to the first and thirdpositions.

For cell 1, cell 2, cell 3 and cell 4 are neighboring cells, and cell 2,cell 3 and cell 4 use the first, second, third, and fourth SS blockpositions, when cell 1 uses a bitmap to notify the actual transmissionposition of the SS block of the neighboring cell of cell 1 to the UEserved by cell 1, the bitmap is: “11110000”, where “1” indicates thatthe SS block is transmitted at this candidate position, and “0”indicates that the SS block is not transmitted at this candidateposition.

For cell 3, cell 1, cell 2 and cell 4 are neighboring cells, and cells1, 2 and 4 use the first, second, and third SS block positions, whencell 3 uses a bitmap to notify the actual transmission position of theSS block of the neighboring cell of cell 3 to the UE served by cell 3,the bitmap is: “11100000”, where “1” indicates that the SS block istransmitted at this candidate position, and “0” indicates that the SSblock is not transmitted at this candidate position.

For cell 4, cell 1, cell 2 and cell 3 are neighboring cells, and cell 1,cell 2 and cell 3 use the first, second, and fourth SS block positions,when cell 4 uses a bitmap to notify the actual transmission position ofthe SS block of the neighboring cell of cell 4 to the UE served by cell4, the bitmap is: “11010000”, where “1” indicates that the SS block istransmitted at this candidate position, and “0” indicates that the SSblock is not transmitted at this candidate position.

The network apparatus notifies the actual transmission position of theSS block of each of other cells to be measured in the form of onebitmap.

When the terminal performs measurement, if the local cell and theneighboring cell are synchronous, the terminal may determine the actualposition of the SS block transmitted by the neighboring cell. Theterminal directly acquires the actual position of the SS block of theneighboring cell based on the timing of the local cell.

Different from the foregoing synchronous situation, when there is asynchronous deviation between the local cell and the neighboring cell,the following manner may be adopted.

The measuring unit 62 is configured to, when there is a synchronousdeviation between the at least one first type of cell and the cellmanaged by the network apparatus,

acquire, the synchronous deviation between the at least one first typeof cell and the cell managed by the network apparatus; and

acquire, the bitmap corresponding to each of the first type of cell, andacquiring the transmission position of the synchronous signal block ofeach of the first type of cell based on the bitmap.

First of all, the network apparatus notifies the terminal of thesynchronous deviation between other cell(s) and the local cellcorresponding to the network apparatus. Correspondingly, when theterminal performs measurement, if the local cell and the neighboringcell are not synchronous, the terminal may determine the actual positionof the SS block transmitted by the neighboring cell based on thenotification information and the deviation of the timings between thecells. The terminal directly acquires the actual position of the SSblock of the neighboring cell to be measured based on the timing of thelocal cell and the timing deviation of the neighboring cell to bemeasured.

For example, as shown in FIG. 3, cell 1 and cell 3 are synchronous, cell2 is 0.5 ms backward offset from cell 1 and cell 3, then the firstcandidate SS block position of cell 2 corresponds to the secondcandidate SS block position of cell 1; and cell 4 is 1 ms backwardoffset from cell 1 and cell 3, so the first candidate SS block locationof cell 4 corresponds to the third candidate SS block location of cell1.

For example, cell 1 notifies the terminal of the time deviation betweencell 2, cell 3, cell 4 and cell 1 respectively, the terminal combinesthe actual SS block transmission position of each of the cell 2, 3 and4, and then the terminal may determine the reception time of actualtransmission SS block of each cell.

In addition, the present embodiment may also provide a processing mannerfor a scenario in which a part of the neighboring cells is synchronouswith the local cell and another part of the neighboring cells is notsynchronous with the local cell:

if there is a synchronous deviation between a first part of the firsttype of cell in at least one first type of cell and the cell managed bythe network apparatus, and a second part of the first type of cell inthe first type of cell is in the synchronous state with the cell managedby the network apparatus; wherein, the first part of the first type ofcell is different from the second part of the first type of cell, andthe first part of the first type of cell and the second part of thefirst type of cell form all the first type of cell;

then acquiring the transmission position of the synchronous signal blockof the first part of the first type of cell based on the bitmap of eachfirst type of cell in the first part of the first type of cell;

and, acquiring, according to the bitmap of the second part of the firsttype of cell, the transmission position of the synchronous signal blockof the second part of the first type of cell.

For example, in four neighboring cells, the synchronous relationshipbetween the neighboring cells 1, 2 and the local cell is synchronous,and the neighboring cells 3 and 4 have a deviation; then, thetransmission positions of the synchronous signal blocks of theneighboring cells 1 and 2 are all set in the bitmap and transmitted tothe terminal apparatus; the synchronous deviation of the neighboringcells 3 and 4, and the bitmap of the transmission position of thesynchronous signal block of the neighboring cell 3, and the bitmap ofthe transmission position of the synchronous signal block of theneighboring cell 4 are all transmitted to the terminal apparatus.Correspondingly, the terminal apparatus performs measurement on theneighboring cells 1 and 2 based on the bitmap of the transmissionposition of the synchronous signal block including the neighboring cell1 and cell 2; and then, based on the synchronous deviation of theneighboring cells 3 and 4 and the respective bitmaps, perform themeasurement at the transmission positions of the synchronous signalblocks of the neighboring cells 3 and 4 respectively.

There is also a processing manner in the present embodiment, that is, nomatter whether there is a synchronous deviation between the neighboringcell and the local cell, the synchronous deviation of the neighboringcell and the bitmap of the transmission position of the synchronoussignal block of the neighboring cell are transmitted to the terminalapparatus.

That is, the measuring unit 62 is configured to acquire the synchronousdeviation between each of the at least one first type of cell and thecell managed by the network apparatus;

acquire the bitmap corresponding to each of the first type of cell, andacquire the transmission position of the synchronous signal block ofeach of the first type of cell from the bitmap.

In this scenario, the synchronous deviation of the neighboring cellsynchronized with the local cell is equal to 0.

Finally, it should be noted that, in this embodiment, the synchronousdeviation of a certain neighboring cell and the bitmap corresponding toa certain neighboring cell may be sent simultaneously or sequentially,which is not limited herein.

It can be seen that by adopting the above scheme, the transmissionposition of the synchronous signal block of the neighboring cell can betransmitted to the terminal apparatus, thereby ensuring that theterminal apparatus can directly measure the neighboring cell at a momentcorresponding to the notified transmission position of the synchronoussignal block of the first type of cell, without performing measurementat other locations, thereby saving terminal measurement time and powerconsumption.
